为研究匹配网络对强耦合发射天线阵列性能的影响,以网络散射理论为基础,在发射耦合天线框架内给出了含匹配网络参数的阵列效率表达式,讨论了网络参数对阵列性能的影响,从而为强耦合有限阵列性能分析提供了条件。最后以3×3有限强耦合平面天线阵为例,计算结果表明,在有限强耦合阵列单元端口增加匹配网络可以改善阵列边缘效应,但采用多种网络参数方法在进一步提高阵列效率方面效果不明显。本文理论和方法为研究强耦合发射阵列特性提供了便利和条件,同时对工程实施和应用具有较强的指导意义。
In order to study the effect of matching network on the performance of the strongly coupled transmitting antenna array, based on the network scattering theory, the array efficiency expression with matching network parameters is given in the framework of the transmitting coupling antenna. The influence of network parameters on array performance is discussed. Thus providing the conditions for the performance analysis of a strongly coupled finite array. Finally, a 3 × 3 finitely strong coupling planar antenna array is taken as an example. The calculation results show that adding matching networks to the ports with finitely strong coupling arrays can improve the edge effect of the array. However, using a variety of network parameters has no obvious effect in further improving the array efficiency . The theory and method of this paper provide convenience and conditions for the study of the characteristics of a strongly coupled transmitting array, and have strong guiding significance for the implementation and application of the project.
